Some guys identify a second gene associated with life extension effects of calorie restriction. This doesn't mean much except that they will probably be able to duplicate the effect without starving people.
I can't wait to see what happens when all this stuff is fully decoded. I predict: 1) they WILL solve aging completely within most of our lifetimes, 2) there will be an attempt to limit the distribution in order to keep the world's population down, and 3) we will see the bloodiest wars ever as a direct or indirect result (I'm guessing direct).
Not to be negative or anything.
